I just acquired a P20 toshoba laptop...nice little rig - 17", dvdrw, etc...

Problem:

Fans will come on, power light on...no blinking lights just solid blue power light.

Tested the ram and cpu elsewhere...they are fine....tried an external monitor(and tried the Fn-F5 to swap displays,etc) no go...

Before I resort to hunting down a motherboard, are there any "known" issues with this? Any troubleshooting tips that I should try?

Thanks
